本文实例讲述了yii去掉必填项中星号的方法。分享给大家供大家参考,具体如下:

如何去掉必填项里的星号呢?

先分析下代码实现:

public function labelEx($model,$attribute,$htmlOptions=array())
{
  return CHtml::activeLabelEx($model,$attribute,$htmlOptions);
}
public static function activeLabelEx($model,$attribute,$htmlOptions=array())
{
  $realAttribute=$attribute;
  self::resolveName($model,$attribute); // strip off square brackets if any
  $htmlOptions['required']=$model->isAttributeRequired($attribute);
  return self::activeLabel($model,$realAttribute,$htmlOptions);
}

Copy after login

当属性是必填的时候,它将渲染额外的CSS类个标记。特别的,它调用CModel::isAttributeRequired来决定属性是否为必填的。如果是,它将添加一个CSS类CHtml::requiredCss (public static $requiredCss='required';)到标签上,用CHtml::beforeRequiredLabel(public static $beforeRequiredLabel='';)和CHtml::afterRequiredLabel (public static $afterRequiredLabel='*';)来装饰标签。

public function isAttributeRequired($attribute)
{
  foreach($this->getValidators($attribute) as $validator)
  {
    if($validator instanceof CRequiredValidator) return true;
  }
  return false;
}

Copy after login

所以要去掉星号 或者换成别的可以再view中直接重新定义CHtml::requiredCss、CHtml::beforeRequiredLabel、CHtml::afterRequiredLabel即可

不显示星号就可这样

<&#63;php CHtml::$afterRequiredLabel = '';&#63;>
<&#63;php echo $form->labelEx($model,'email'); &#63;>

Copy after login

希望本文所述对大家基于Yii框架的PHP程序设计有所帮助。
